Bus Engines

Going back a great many years and from what little memory I have recollects there was a story of a new type of bus engine with non-removable cylinder heads.
Any ideas?

Did'nt the Leyland Buffalo have an engine like that at one time?

Leyland Buffalo did the trick and not losing the marbles just yet as I did wonder about this one, seems it was called the 500 fixed head engine so thanks to dmackay for that.

So they took a bunch of engines into the test lab and tried to get them to mis-behave. Only to everyone's amazement they all ran perfectly. It wasn't until later that Graham realised that the engines they'd been given were effectively 'blue-printed'. When they checked the tolerance on the production engines they were all over the place--hence their appalling durability.

Enough said!

Not much found for this fixed head engine -

The prototype engine for the Leyland Titan was a turbocharged version of the Leyland 500 series, although this was changed to Gardner 6LXB for production after concerns over fuel economy and reliability of the 500 nicknamed the headless wonder.

Bedford used to offer a Leyland engine before they made their own 466 cu in diesel. Did the 'Big Bedford' (S-type) use this engine?

Originally fitted with a 110bhp 6-cylinder petrol engine.
Diesel option in the form of the Perkins R6 arrived in 1953.
Bedford's own diesel in 1958.
The S-type was discontinued in late 1959.

Leyland National had the fixed head 500 engine also.

Hi Im David

Bedford used the 0400 Leyland Engine more commonly found in the Comet and the Albion Chieftain / Clydesdale and as the 410 Turbocharged in the Reiver. To my knowledge, Bedford never used Perkins engines, Leyland however did in the Boxer.
